Hi there! I want to get the most out of battery life on my 1520.3. I've heard a lot of stories that battery saver actually eats more battery than it saves. I personally prefer it always on, but I was wondering if it makes a difference if I let it run in the background, have it run with battery saver on (always allowed), or disable it in the background? Kind of a weird option, but would it make any difference? I noticed my battery discharge goes from 4% to 2.4% an hour with it disabled. But possibly because I turn off some battery tracker? Thanks!
